The
safety card
}
Activates safety functions
}
Monitors safe motion sequences.
}
Signals the status of safety functions to the safety control system
}
In the event of an error, activates the safe pulse disabler which is integrated within the
servo amplifier and shuts down the power to the motor
}
Passes the brake command to the servo amplifier that is executing the travel command
}
Has a second shutdown route in order to implement categories SIL3 or PL e.
}
Has a dualpole output to control an external holding brake. The brake can be tested
using the safety function "safe brake test SBT".
}
Has a connection for an external encoder (incremental encoder or encoder with SSI
signals can be selected). For details of the safetyrelated assessment when using an
external encoder see Chapter 8 "Technical Details", under "Safetyrelated characteristic
data".
The
servo amplifier
}
Removes the power to the motor, if the safe pulse disabler is activated, switches the
motor to torquefree and can also control an internal motor brake.
The
safety control system
}
Activates the safety functions via inputs on the safety card
}
Evaluates signals from safety devices, such as:
– ESTOP pushbuttons
– Safety gates
– Light beam devices
– Twohand buttons
}
Processes the safety card's status outputs
}
Safe interconnection between safety card and safety control system
}
Fault detection (shorts across contacts, short circuits) on signals between the safety
control system and safety card, and initiation of measures
Configurator PASconfig SDrive
}
Configuration and parameterisation of the safety card
}
Safe upload and download of the configuration file
}
Online display of the status of the safety functions
}
Display of error stack
}
Ability to save the configuration to SD card
4.2
Inputs and outputs
The safety card has safe inputs and outputs which
}
can be freely assigned
}
can be assigned fixed functions.
Inputs I0 to I6 can be used to activate the safety functions.
Outputs O0 to O3 can be used to acknowledge the status of the safety functions.
